Generalized paging schemes for cellular systems Kim, Tae Kyung
Abstract
The problem of locating a mobile vehicular user in a cellular communication system is addressed. Two location area (LA) paging schemes, called generalized paging with time-stamp and generalized paging without time-stamp, are proposed to determine the location of a user within an LA and are compared to the Selective paging scheme. The mobility of a user is modelled by a directional random walk process and the user location is registered using a dynamic LA-based location updating scheme. It is found that generalized paging with time-stamp and generalized paging without time-stamp can significantly reduce both average paging delay and traffic when compared to Selective paging. The sensitivity of the two generalized paging schemes to uncertainty in user mobility parameter values, such as the mean speed, mean velocity hold time, and angular deviation parameter, is studied. Generalized paging with time-stamp is found to be very sensitive to uncertainty in user mean speed whereas generalized paging without time-stamp is not very sensitive to changes in all three parameter values. Two multicasting schemes called generalized multicasting with time-stamp and generalized multicasting without time-stamp, based on the two generalized paging schemes, are proposed. The two generalized multicasting schemes' performances in terms of the average paging delay and traffic improve significantly as the number of users within the service area is increased.

Description |
The problem of locating a mobile vehicular user in a cellular communication system is
addressed. Two location area (LA) paging schemes, called generalized paging with time-stamp
and generalized paging without time-stamp, are proposed to determine the location of a user
within an LA and are compared to the Selective paging scheme. The mobility of a user is
modelled by a directional random walk process and the user location is registered using a
dynamic LA-based location updating scheme. It is found that generalized paging with time-stamp
and generalized paging without time-stamp can significantly reduce both average paging delay
and traffic when compared to Selective paging.
The sensitivity of the two generalized paging schemes to uncertainty in user mobility
parameter values, such as the mean speed, mean velocity hold time, and angular deviation
parameter, is studied. Generalized paging with time-stamp is found to be very sensitive to
uncertainty in user mean speed whereas generalized paging without time-stamp is not very
sensitive to changes in all three parameter values.
Two multicasting schemes called generalized multicasting with time-stamp and generalized
multicasting without time-stamp, based on the two generalized paging schemes, are
proposed. The two generalized multicasting schemes' performances in terms of the average
paging delay and traffic improve significantly as the number of users within the service area is
increased.
